Research on teaching method of waste pipe-network design in environmental engineering

随着社会经济的发展,城市排水管网系统的规模越来越大,逐步发展为一个复杂的大规模管网系统。如何设计和维护这样庞大的排水管网系统,不仅从根本上影响着管网系统的投资及维护管理费用,也会对城市环境保护和工业企业的发展有着深远的影响。文章在课程设计教学中对排水管网设计的两种方法,图表法和最优化法进行了比较和分析,介绍了如何用最优化法对教材中的实例进行设计。通过课程设计的实践表明,最优化法有助于学生掌握影响管网设计的关键水力要素的变化规律,加深对管网设计本质的理解。因此,有必要在给排水工程课程设计的教学中,引入最优化的理论和设计方法。 With the development of society economy,the scale of the waste pipe-network have become more and more large and the structure of the system is also more complex.How to design and maintain the large waste pipe-network will ultimately affect the system capital and maintained cost,as well as deeply affect the environment protect of the city and the development of the industry.In this paper,two methods in waste pipe-network design,i.e.the chart method and the optimization method,were analyzed and compared,and then how to design the example in textbook with the optimization method also was introduced.The practice of course design indicates that the optimization method is helpful for students to master the change rules of the key hydraulic factors and to deepen understanding the essence of pipe-network design.Therefore,it is necessary to introduce the theory and method of the optimization in the course design teaching of the water and waste engineering.广西民族大学校级教改课题资助项目(2011XJGB19);广西基础化学实验教学示范中心教学研究专项(Y21
